ADJUSTABLE ROOF.l

SPECIFICATION forming part of Letters Patent No. 313,559, dated March 10, 1885.

v Application iled June 2l, 1884. (No model.)

To all whom, it may concern:

Be it known that I, Louis DAVID VOGEL, of Boone, county of Boone, and State of Iowa, have invented a new and useful Improvement in Adjustable Roofs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use it, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in folding roofs in which sections of the same are folded together and disposed of or spread out at will by means of chains and pulleys.

The objects of my invention are to spread out a great surface of roof and fold the same in the shortest time possible, and to dispose of the necessary friction, so as to prevent jamming. I accomplish this by means of the mechanism shown in the accompanying drawings, in which- Figure lis a plan view of two sections of sheds provided with my invention. In one of the sections the roof is shown folded under the cupola and in the other spread out. Fig. 2 is a front elevation of Fig. l, showing the folding and opening gear. Fig. 3 is a detail of the roof-sections and manner of manipulating the same. Fig. itis a detail of the rafters provided with the grooves for the roofsections. Fig. 5 is a detail view of rafters with attachments.

In describing the operation and parts of my invention I will take brick yards or sheds; but it is obvious that I do not confine myself to them.

In the drawings, A represents the roof-sections, Fig. 3, to which are attached the end pieces, B and B, in the manner shown in the drawings.

In the piece B are the slots B2,to engage the pins B3 in piece B in the following manner: When the lower section moves, these pins engage the slots in the section above it, and so on, the sections followingdown the grooved rafter C in succession. The end pieces B extend up so as to form a shoulder, which engages the lower portion of the piece B of the section above, and thus when the folding is commenced the shoulders operate much as the pins do in unfolding. The sections Aare held in the grooves in O by the batten-pieces B, which project on either side and engage the grooves O in rafter C. Instead of these batten-pieces, I sometimes use an iron shoe of any suitable form.

C is a rafter thatis provided with the grooves C', which are grooves running along the side of the rafter, as shown in drawing Fig. 4. About the center of the shed is the windlass D, and above it, swung on the center posts, is the shaft F, which is provided at every section length with a pulley, F. From the windlass runs an endless chain, E, which connects the windlass and shaft, and from the pulleys on the shaft extend the endless chainsV E E to the stationary pulleys G.

To the chain E is attached the rod H, which is swung between the slotted pendants I I. These pendants are fastened fixedly to the lower end piece of the lower section, A, as shown in drawings. In this way the sections are brought down with the least friction, as the edges are kept off the rafter by the rod being swung between those of different sections, and the chain attached to the center of said rod.

J is a roller, on which is rolled a canvas curtain or fiap to keep out driving rain. g This roller J is connected to the pulleys G and operated by them so as to operate as the roof does and from the same motor, thus decreasing the number of laborers.

The operation of my invention is as follows: The windlass is operated, and as the chainsE E are connected immediately or mediately with it they are operated simultaneously, and, carrying the lower section by means of the pendant I,either fold or unfold the sections as the chain moves.

Having thus fully described my invention, what I claim is- 1. In a roof, the sections A, provided at their ends with the pieces or shoulders B B, and a projection on their sides to engage the slots C in the rafter C, substantially as and for the purpose set forth and described.

2. In a folding roof, the combination of the slotted pendants I7 the connecting-rod H,

Ico

and the endless chains E, substantially as and I end piece or shoulder, B, provided with the for the purpose set forth and described.

3. The combination of the windlass D, the chains E E E, pulley-shaft F, and pulleys G 5 with the roof-sections A, having the pendants I and connecting-rod H, substantially as and for the purpose set forth and described.

4. The combination of the sections A, having at their ends the shoulders B B', and proxo jections at their sides to engage the grooves C in rafter (l, with the Windlass D, chains E E E, pulley-shaft F, and pulleys G, substantially as and for the purpose set forth and described.

15 5. In a folding roof, the combination of the slot B2 and beveled on its under side, with the end piece or shoulder, B', provided with the pin B3 on its upper surface to engage slot B, and having its upper side beveled to coincide 2o with shoulder B of section above it, substantially as and for the purpose set forth and described.

In testimony that I claim the foregoing I append iny signature.-

l LOUIS DAVID VOGEL.
